CONSTRUCTION OF SHIPS.

SPECIFICATION forming part of Letters Patent No. 300,714, dated J'une 17, 1884.

' Application nien April 22; 1884. (No model.)

To aZZ whom it may concern:

Be it known that I, TrTUs LANGILLE, a snbject of the Queen of Great Britain, and a resident of Mahone Bay, in the county of Lunen- 5 burg, Province of Nova Scotia, and Dominion of Canada, have invented certain new and useful Improvements in the Construction of Ships; and I do hereby declare that the following is a full, clear, and exact description of the invention,which will enable others skilled inthe art to which it appertains to make and use the same, reference being had to the accompanying drawings, which form a part of this speciication, and in whichthrough the middle of a vessel having thchold constructed according to my improvement. Fig. 2 is a vertical cross-section of the same on an enlarged scale. Fig. 3is a plan view of the floor-beams, and Fig. 4 is a detailed view of the flooring, showing the construction of the removable flooring-strips.

Similar letters of reference indicate corresponding parts in all the figures. v

My invention relates to an improved construction of the holds of vessels,which has for its object to prevent the loss incident to the drainage in cargoes of sugar, molasses, and other goods of a similar nature. In cargoes of this class the loss by drainage on long ocean'- voyages averages about ten per cent., as the sugar or molasses which drains from the casks or hogsheads runs to the bottom of the hold, where it mixes with the bilge-water during the passage, and is pumped overboard with it. By my improved construction of the hold, as hereinafter more fully described and claimed, this loss is entirely obviated, and all the drainage is saved in as good condition as the original contents of the casks or hogsheads. This construction also enables vessels to carry cargoes of grain, salt, or other dry and perishable cargoes in a good and perfectly dry condition, without damage from sea water or bilge-water, and it has this additional advantage, that it adds greatly to the strength of the ship, and, by constructing the same with a water-tight ceiling, makes it impossible for the ship to sink, even if it should spring a leak in 5o the bottom.

In constructing the hold of a vessel accord- Figure 1 is a longitudinal sectional view,

ing to my improvement care must be taken in the first place to calk the vessel carefully and make it tight. The ceiling and inside skin is also carefully calked from the keelson up to the air-streak and made perfectly watertight, and at the ends of the vessel there are deadwoods and timbers fitted to the keelson, the ends of the ceiling being fitted to those timbers and calked, whereby the fore and aft parts of the vessel are both strengthened and made water-tight.

In the bottom of the hold, impinging at one end upon the keelson A and at right angles thereto, are placed thick planks B, set on edge and extending out to the 'turn of the bilge. These planks are setat a distance of about twenty-two inches from one another through the length of the hold, the planks being made tapering on their under side, so as to cometo a point, C, at the turn of the bilge. They are held in place edgewise by substantial cleats E, which are' spiked or otherwise fastened to opposite sides of the keelson, and also by the cross-beams F, which are let into the sides of the planks B, as shown more clearly in Fig. 3, the planks being mortised on their sides to receive the ends of the beams F. Upon these beams rest the removable flooring-planks G, which are spaced apart, so as to leave narrow open spaces H. When the vessel is to be used for shipping grain, salt, or similar merchandise in bulk, the openings II are closed by strips I, the sides of which are beveled, as shown in Fig. 4, to fit the beveled sides of adjacent flooring-planks G. The top of planks B is about three inches above the level of the flooring G, which enables the casks resting on their quarter-hoops upon the ribs formed by the planks B to clear the ii/ooring with their bilge' or belly. The planks B are cut away on their under side to form apertures b, through which the drainage that drops downthrough the slots or openings Hin the flooring is permittedto run back to the well K. There may be one or more of these collecting-wells, each consisting of a hollow block sunk down through the ceiling and timbers-one on each side of the keelson-forming basins or reservoirs to receive the drainage, and from which this may be pumped up whenever desired and filled into empty casks which are carried for the purpose.
